produce smooth, continuous muscle contraction
wave summation results and muscle twitches overlap.
the glass allows short wave lengths of radiation to enter, but reduces the amount of long-wave length radiation that escapes
They call it the Primary wave or a P-wave

primary
The primary factor that determines the velocity of a wave is the medium through which the wave is traveling.
Wave summation releases more calcium and increases the force of contraction by increasing the firing rate of motor neurons (The second contraction takes place before the first is completely at rest) so each stimulation adds up. This is all within ONE MUSCLE FIBER. Recruitment is the calling up multiple MOTOR UNITS, in order to increase the force of contraction. t has a size principle (those with small diameters, the more delicate ones are called first, then the larger and so on.) There is no added calcium ions as in wave summation. They usually occur together. wave summation can cause tetanus, while recruitment cannot.
Primary Wave (P wave)
A primary wave is a strong vibration or wave that hits earths surface (P) and a secondary wave (S) is a wave that hits soon after but not nearly as big.
The primary body wave that is a longitudinal wave is the P-wave (primary wave). It is the fastest seismic wave and travels through the Earth's interior by compressing and expanding the rock in the direction of the wave's propagation.
A wave function is a mathematical equation that describes the behavior of a wave. It includes information about the amplitude, frequency, and wavelength of the wave.
Wave summation occurs when a muscle is stimulated rapidly enough that it does not have time to completely relax between stimuli, causing the contractions to combine or "summate" to produce a stronger muscle contraction. This phenomenon can occur during repetitive or sustained muscle activity, leading to increased muscle force production.
